Dependencies

from django.shortcuts import render
from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
from django.contrib.auth import authenticate
from site_user.models import User

This code will revoke username and password from session when we are at login page

def home(request):
    if request.session.has_key('username') and request.session.has_key('password'):
        username = request.session['username']
        password = request.session['password']
        context_dict = {'username': username, 'password': password}
        return render(request, 'sadmin/login.html', context=context_dict)
    else:
        context_dict = {'username': '', 'password': ''}
        return render(request, 'sadmin/login.html', context=context_dict)

The following code is used for user authentication. Here 'is_remember_check' checkbox field from HTML file

@csrf_exempt
def login(request):
    if request.method == "POST":
        if request.POST['is_remember_check'] == 'true':
            request.session['username'] = request.POST['username']
            request.session['password'] = request.POST['password']

        user = authenticate(username=request.POST['username'], password=request.POST['password'])

        if user is not None:
            return JsonResponse({'result': request.POST, 'status': True})
        else:
            return JsonResponse({'result': request.POST, 'status': False})

AJAX call from login page

function login(){
    remember_checkbox_value = document.getElementsByName('remember')[0].checked;
    username = document.getElementsByName('username')[0].value;
    password = document.getElementsByName('password')[0].value;
    var post_data = {username:username, password:password, is_remember_check:remember_checkbox_value};

    $.ajax({
                url: '/sadmin/login/',
                method: 'POST',
                data: post_data,
                dataType: 'json',
                success: function (response) {
                        if (response.status){
                        alert("User login is successful");
                        window.location.reload();
                        }
                        else{
                        alert("User login is not successful");
                        window.location.reload();
                        }
                }
        });
}

HTML Code
